To all whom it may concern:

Be it known that I, Axnr, ll/former, manufacturer, subject of'the l iingdom of Denmark, residing at No. 5 Rosenborggade,

Copenhagen, Denmark, have invented .cer

tain new anduscful Improvements in De vices for Spinning Screw-Formed Nmdmgs or Curls of Hair or the like Material; and

I do hereby declare the following to be a full, clear, and exact descriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac companymg drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates .to an arrangement in connection with spinning machines for manufacturing curls, i. a. screwformed windings of hair or the like material. By means of the said arrangement the material, after having been previously twisted into a smooth cord, is through an excessive twisting (overtwisting) caused to curl up so as to assume the shapeof a screwfo-rmed winding. The last portion of the spinning i. c. the curling process, which has up to the present been effected by hand, is

now done automatically, which means saving in labor and space.

tate in a bearing 4 and carrying a driving pulley 5. To the axle 3 is fixed a plateshaped head on which are arranged a number of pins, of which two, 7 and 8, are shown on the drawing. Upon these pins may he slipped rollers, sleeves or the like. The head 6 is further provided with a guiding device 9 for the smooth twisted cord issuing from the hollow axle 3, the upper edge of said guiding device being about level with the centerline li -A of the apparatus. The guiding device may consist of a solid block or a suitably bent plate, a short piece of tubing, a ring or the like. The smooth Serial o. 789,054.

twisted "cordj2 is, after having l'eftthe 1161- jlowaxle 3, earned over the pins 7 andS and thence over the guiding device 9 in the manner shown in Fig.2,

Through the rotation of the axle 3 the nateria-l2, 2 is twisted into a smooth cord corresponding'to portion 6, Fig. 1, and with" theyiew of transforming this cord into .thefinished material which has the shape of a screw-formed"winding, thespecial features of the invention'consist partly in the arrangement of the guiding device 9 with its edge 10 at such a place in relation to the last guiding pin 8, thatthedirectionof the cord-between said pin and the edge 10 and the direction of the cord after having passed the edge 10, forms an angle ofabout 90, and partly in the cord being immediately after having passed the edge 10 subjected to a hard twisting (overtwisting). Another special feature consists therein that the finished material is wound upon a reel.

were or? Him onnixnj i If desired, and for facilitating the process 1 of curling, the edge 10 may be arranged at a small angle with the center line so as to impart to the cord a slight direction to one side. Immediately after leaving the edge 10 of the guiding device the cord is subjected to a further twisting as described below, and through this new twisting it will curl up and assume the shape of a screw-formed winding as shown at 16, Fig. 2, corresponding to portion 0, Fig. 1. After leaving the edge 10 the curled up material is carried through another hollow axle 12 arranged to-rotate in a bearing 11, a driving pulley 13 being fixed upon the said axle 12. To the axle 12 is attached a fork 14; whose prongs form bearings for a reel 15. Vhen driving power is applied to the pulley 13 the axle l2 and with it the fork 1 1 and reel 15 will rotate, and through a device not shown on the drawing the reel is further arranged to turn on its own axis.

The extremity of the cord is secured to the reel 15, and the axle 12 is made to rotate at a speed somewhat greater than that of the axle3. As the curls or windings of the "cord are formed the material will move forsituated approximately inline with the longitudinal axis of said shaft and at approxibe fixed to the axle3. A previously smooth twisted cord can for instance be wound on a suitable reel andthence be carried toan independent device provided with the guiding means for carrying it at approximately 90 over the edge of the guiding device in the same manner as described above, the said guiding device being in this case statlonary.

I claim t- 1. Ina device for curling hair and like material, the combination with a hollow curling shaft, of guides, for the twisted uncurled portion of the material to be curled,

mately right angles to the latter.

2. A device for curling hair and like Inaterial comprising a'hollow rotatable shaft having its axis in alinement with the axis of the twisting member, a head caried by the latter, and guides on said head arranged to feed the twisted material to said shaft and in a pathat right angles to the longitudinal axis of the latter.

3. A device for curling hair and like material comprising a hollow rotatable member ada ted to twist the material, a hollow rotata le shaft having its axis in alinement with the axis of the twisting member, a head carried by the latter, guides on said head arranged to feed the twisted material to said shaft and in a path at right angles to the longitudinal axis of the latter, and a storage reel for the curled material mounted on the hollow shaft.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
